Abstract

A transmission and/or reception process with high channel capacity uses a multiple transmitter and/or receiver system, and signal processing undergoes phases of temporary switching-off. Also disclosed arm corresponding transmitters and/or receivers, as well as a mobile terminal. In order to provide a process, a device and a mobile terminal of the above-mentioned type which improve communication reliability with high spectral efficiency using multipath propagation, it is proposed that the mixer units (5) be initialised when signal processing is turned on.

Claims

1. A transmitting and/or receiving method with high channel capacity, comprising:

using a multi-transmitter and/or multi-receiver system in which signal processing is subject to phases of temporary disconnections such that when the signal processing is switched on, mixer units are initialized.

2. The method as claimed in claim 1, wherein a particular form of temporary disconnection in a form of transmitting and/or receiving in defined time slots is used.

3. The method as claimed in claim 1, wherein a reset signal is used which simultaneously addresses the mixer units of data processing paths arranged in parallel.

4. The method as claimed in claim 1, wherein a defined preload is used in the mixer units.

5. The method as claimed in claim 1, wherein within the each of the mixer units, dividers or frequency converters, respectively, are driven.

6. The method as claimed in claim 5, wherein regenerative dividers are used as the dividers or the frequency converters, respectively.

7. The method as claimed in claim 6, wherein the reset is converted via a switch in at least one feedback branch of each regenerative divider.

8. A device with high channel capacity in a form of a multi-transmitter and/or multi-receiver system in which antennas arranged in spatially distributed manner, comprising:

signal processing configured to be disconnected; and

an initialization circuit which is connected to mixer units on individual receiving and/or transmitting paths for initializing the respective mixing units when the signal processing is switched on.

9. The device as claimed in claim 8 wherein the initialization circuit is configured for sending out a reset signal which simultaneously reaches the mixer units of the data processing paths, arranged in parallel, of the device.

10. The device as claimed in claim 8, wherein regenerative dividers are provided for adjusting arbitrary divider ratios in the mixer units.

11. A mobile terminal with high channel capacity which is arranged in a form of a multi-transmitter and/or multi-receiver system, in which antennas arranged in spatially distributed manner are provided, comprising:

a device having signal processing configured to be disconnected; and

an initialization circuit which is connected to mixer units on individual receiving and/or transmitting paths for initializing the respective mixing units when the signal processing is switched on.
